SUMMARY 

I work as a photographer at an "old-time" photo studio. The most popular theme we offer is 
the Wild West, and we have the usual selection of props for the period: guns, whiskey 
bottles, money bags, playing cards and so on. The other day I decided that it would be fun to 
have some sticks of dynamite as well. 

I did a Google image search to find out what dynamite typically looks like and found that its 
appearance takes a number of different forms depending on the period, manufacturer, etc., 
so I picked one that is fairly stereotypical. 

Dynamite was invented by the Swedish chemist Alfred Nobel and patented in 1867. It 
consists of nitroglycerin and an absorbent binder formed into sticks and covered with a 
paper wrapper. A quick check with Wikipedia reveals that the most common standard size 
for dynamite is a stick VA" in diameter and 8" long.

I designed the wrapper for my dynamite in Inkscape . It's included here as a PDF file.

Step 1 — Make wood cores and wrappers 






• Cut your dowel into pieces 8" long. 

• Download the PDF file at the top of this guide and print it out on colored paper (preferably 
red because it looks more dangerous, but beige or yellow wrappers are sometimes used 
also). 

• I used red construction paper because I wanted its slightly coarse surface. Since 
construction paper typically comes in sheets that are 9"x12", I had to trim the paper to 
8 1 /2"x1 1" first so that it would fit in my printer. 

• After you've printed them, cut each sheet in half lengthwise to make two wrappers. Each 
one will cover a VA" dowel perfectly.

Step 2 — Drill hole for fuse 




• Use a center punch or nail to put a dimple in one end of the dowel and drill a pilot hole. 

• Enlarge the hole to the desired diameter. I used W cord, so I drilled a 5/16" hole to provide 
some clearance. 

• The hole doesn't have to be very deep; V2" is plenty. 
Step 3 — Glue wrapper around dowel 




• Turn one of the wrappers over and spread a thin layer of Elmer's glue along the bottom 
edge. Don't go all the way to the ends; just cover an area in the middle that matches the 
length of the dowel. 

• Place the dowel on the glued edge. 

• Turn the assembly over and smooth the edge down with your fingers. If you have used a 
nice thin layer of glue, it will grab and set in a minute or so. Keep smoothing the edge down 
until it does.

Step 4 




• Spread a thin layer of glue over the rest of the wrapper. I suppose that you could use a 
brush for this, but fingers are a lot easier to clean than a brush is! 

• Spread the glue as thinly as possible so that when you roll it up the glue won't ooze 



out from under the edge.

Step 5 




• Roll the wrapper around the dowel. 

• Smooth the edge down as before, and keep smoothing it for a minute or so until the glue 
grabs.

Step 6 — Finish the ends 




• Trim the ends of the wrapper a bit if necessary so that they will fold down over the end of 
the dowel with no excess. 

• Start at the edge of the paper and fold the end down a bit at a time as you work your way 
around. 



Step 7 




• Glue the end flaps down with hot glue. 

• Try not to use too much glue, but if some does ooze out that's ok. It will just look 
like the dynamite is leaking nitroglycerin. Mwahaha!

Step 8 




• On the end that will have the fuse, apply hot glue to the wood and then fold the end of the 
wrapper down. 

• Poke the excess paper into the hole with a screwdriver or similar tool. 
Step 9 — Add the fuse 




• Cut about a 5" or 6" piece of braided cord for the fuse. (Unless you're one of those short- 
fuse people...)

Step 10 




• Fill the hole with hot glue. 

• Poke the fuse in with a screwdriver. 

• Put some Elmer's glue on the free end of the cord and work it into the fibers so that the 
cord won't come unraveled. Fuzz the end out a bit before it dries, though; it looks more 
dangerous that way. 



Step 11 




• A finished stick of dynamite. 

• Now make some more!

Step 12 — Make a bundle of dynamite sticks 




• What do you do when you have several sticks of dynamite? Make a bundle, of course! 

• Start by laying three sticks side by side. Glue them together with hot glue. 

Step 13 




• Place two more sticks on top and draw a light pencil line where the sticks meet to help you 
in placing the glue for the next layer. 

• Apply hot glue just inside the pencil line on the outer stick, and some on the inner stick as 
well. Press the new stick into place.

Step 14 




• Turn the assembly over and repeat the process on the other side. 



Step 15 




• Nowadays, bundles of dynamite are held together with adhesive tape, but that wouldn't 
look right for the 1880s. Sisal twine will look much better. 

• Wrap the twine around the bundle five or six times and tie a knot. I put a dab of glue on the 
knot to keep it secure. 

• If your bundle of dynamite is going to be handled a lot, glue the string to the sticks with 
dabs of Elmer's glue. Apply the glue sparingly and work it in between the strands so that it 
is not visible when it dries. 

• Tie the other end of the bundle in the same way.
